Water Detarium macrocarpum regularly during the growing season, allowing the top few centimeters of soil to dry out between waterings. Reduce watering in cooler months, but do not let the soil become completely dry.

Ensure good drainage to prevent root rot, especially in containers.

Prune Detarium macrocarpum to maintain its shape and size, and to remove any dead or damaged branches.

Light pruning can be done at any time, but heavier pruning is best done in late winter or early spring before new growth begins. This encourages bushier growth.

Propagation of Detarium macrocarpum is typically done through seeds, which require scarification or soaking before sowing. Stem cuttings can also be attempted, but are generally more challenging to root.

Cuttings should be taken from healthy, mature plants in spring.

Repot Detarium macrocarpum every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix. Repotting is best performed in spring before the start of the active growing season.

Choose a pot that is slightly larger than the current one.
